HART C. HUBBELL, OF NAUGATUCK, CONNECTICUT.

IMPRQVEMENT IN WHEELS FOR VEHICLES.

Specification forming part of Letters Patent No. 157,178, dated November 24, 1874; application filed December 16, 1873.

To all whom it may concern:

Be it known that I, HART G. HUBBELL, of Naugatuck, county of New Haven, State of Connecticut, have invented an Improved Carriage-Hub, of which the following is a speciiication:

My invention relates to that class of hubs on which iron flanges are used to form the mortises for the spokes, While the center is of wood; and consists of a double tier of crosst-ies between the spokes connecting the lian ges,

. and on which the spokes have a bearing or shoulder, allowing the tenons of the spokes to touch each other in the grooves in the wood center at the inner circumference of the flan ges, and midway between that and the periphery of the flanges, the end of the tenon bottoming on the wood center, the object being to gain increased bearing-surface on the iron for the spokes, to increase the size of the mortise, and strengthen the hub.

In the drawing, Figure 1 is a cross-section 5 Fig. 2 is a longitudinal section.

A is the Wood center of hub 5 B and B, the anges; C and C, the double ties. D is the groove in the wood center. E is the bevel of the back of the mortise; a and b, points Where the spokes meet and touch each other.

The iianges B and B are similar in form to many now in use for supporting the sides of the spokes. These dan ges are united together by a double row of ties, the outer row coming to a knife-edge at a little less than half the whole width of the flanges toward the center. The inner ties are formed by contracting the mortises to give width to the outer edge of the same, which gives another bearing to the spokes besides the usual one on the periphery, and gives meeting points for the spokes at the center of the flanges latitudinally, and at its inner circumference, beside the bearing on the iron. The end bears on the wood center. The back Ilan ge is beveled to contract the mortises at the bottom, and to help keep the spokes Afirm in the mortises.

What I claim as new, and desire to secure by Letters Patent, is

A hub-band with the double tier of ties, C and C, connecting the flanges B and B, as and for the purposes set forth.

In testimony whereof I have signed my name to this specilication before two subscribing Witnesses.

HART C. HUBBELL.
